Hardware Description 31
Combo Ports
A combo port is a single logical port with two physical connections:
• A RJ-45 connection for Twisted Pair copper cabling
• A SFP connection for various fiber-based modules
Only one of the two physical connections of a combo port may be used at any one time. Port
features and available port controls are determined by the physical connection used.
The system automatically detects the media used on a combo port, and utilizes this information in
all operations and control interfaces.
If both RJ-45 and SFP are present, and a connector is inserted in the SFP port, the SFP port is
active, unless the copper connector of the Base-T port of the same number is inserted and has a
link.
The system can switch from the RJ-45 to the SFP (or vice-versa) without a system reboot or reset.
Physical Dimensions
The device has the following physical dimensions:
• Height — 44 mm (1.73 inch)
• Width — 440 mm (17.32 inch)
• Depth — 255 mm (10.03 inch)
LED Definitions
The front panel contains light emitting diodes (LED) that indicate the status of links, power
supplies, fans, and system diagnostics.
